This International Standard describes a method, carried out under standard conditions, for preparing and storing a sample of a multicomponent coating system and subsequently assessing its pot life by measuring a particular property/ies. Reactive systems curing within a short period of time, e.g. 3 h, will have the end of their pot life so near to the gel point that they will need to be tested for that particular property in accordance with ISO 2535. Special "low temperature" grade systems will need to be tested at a lower specified temperature to reflect the conditions under which they will be used in practice. Additionally, it can be a requirement to determine pot life at a specified temperature or temperatures in order to cover a range of practical conditions under which a paint will be used. The method can be carried out either as a pass/fail test by determining the particular property/ies after a specified period of time, or as determination of the pot life by repeating determinations at convenient intervals of time. This International Standard is not intended for in situ control of products during their application. It is intended to determine "pot life" in the laboratory.
